bug(android): Initial suggestions when starting a new field are not always `Initial cased`

**Describe the bug**

From a team review of the Keyman for Android UX (#7161)

When you start a new text field, the keyboard appears in the shift layer, as expected, but the suggestions presented are out of sync with the keyboard's selected layer, and do not show Initial case as expected.

Typing a letter, then backspace, shows the expected behaviour.

**Screenshots**

The following video illustrates the issue well enough: note how after clearing text, the predictions are `the`, `to`, and `a`. After typing `Oops` and then deleting it, you then get `The`, `To`, and `A` which are the expected predictions.
