[Functions] Removing all deployments when there exists at least one active deployment with pending deployments results in an "orphan function"

### 👟 Reproduction steps

1. Create a function manually

2. Wait for it to build

3. If we delete the deployment, when there is only one deployment regardless of pending status (like building...) or active, all will be good and we will get something like this

4. BUT IF WE DELETE ALL DEPLOYMENT when there is more than one deployments, like this (including pending ones like the those with "Building / Waiting / etc" status:

5. ... we will get a 404 error page, and ended up with orphaned functions, when we click on these functions we will get the 404 error on the specific function we choose

CLICKING THE FUNCTION will result in 404

AND WE DON'T HAVE THE OPTION TO DELETE THESE ORPHANED FUNCTIONS

### 👍 Expected behavior

It should instead be like the case where we have no deployments yet (like the situation when we only have one deployment and we delete it)

### 👎 Actual Behavior

We get a 404 error page, and ended up with orphaned functions, when we click on these functions we will get the 404 error on the specific function we choose

CLICKING THE FUNCTION will result in 404

AND WE DON'T HAVE THE OPTION TO DELETE THESE ORPHANED FUNCTIONS
