TreeView: On touch devices, when disallowEmptySelection is enabled, the TreeView component does not revert to selectionBehavior="replace" as expected

### Provide a general summary of the issue here

Hi, I noticed something potentially unintended regarding the behavior described in the [TreeView documentation](https://react-spectrum.adobe.com/react-aria/Tree.html#item-actions):

On the docs -> On touch devices, the action becomes the primary tap interaction, and a long press enters into selection mode, which temporarily swaps the selection behavior to "toggle" to perform selection (you may wish to display checkboxes when this happens). Deselecting all items exits selection mode and reverts the selection behavior back to "replace".

However, when using disallowEmptySelection, it's not possible to deselect all items—meaning the TreeView never exits selection mode, and thus never reverts back to selectionBehavior="replace".

This leads to inconsistent behavior on touch devices when disallowEmptySelection is enabled, as the temporary selection mode becomes effectively permanent. It also causes the onAction to not be triggered.

Would love to know if this is the intended behavior, or if a workaround is recommended in this scenario

### 🤔 Expected Behavior?

When disallowEmptySelection is enabled:

The TreeView should still be able to exit selection mode, even though it prevents a completely empty selection.

For example, exiting selection mode could occur after the user performs a tap (primary action) or long press on a selected item—without requiring the selection to be empty.

Once selection mode is exited, selectionBehavior should revert to "replace" so that single-tap actions behave as expected again.

### 😯 Current Behavior

When disallowEmptySelection is enabled:

The TreeView enters selection mode as expected on long press.

However, because at least one item must remain selected, the user can never fully deselect all items.

As a result, the TreeView never exits selection mode, and selectionBehavior remains stuck in "toggle" mode.

This leads to a permanent change in interaction behavior, breaking the expected revert to "replace" and causing the onAction passed to the TreeView to not be called.
