🐞 cmd+delete for deleting terminal become inactive after trying to delete a file with the shortcut

[Cubik65536]

Description

In PR #1329, some improvements on the focus system are added so commands like cmd+delete for deleting current terminal or selected file can be handled more easily. But, after the user selects a file and try to use cmd+delete to delete a file (which will not work because it's not implemented), cmd+delete for deleting the terminal will also stop working.

To Reproduce

1. Open a project with CodeEdit
2. Select a terminal tab
3. Use cmd+delete to delete the terminal (it will work as intended)
4. Select a file
5. Use cmd+delete to delete the file (it will not work because it's yet to be implemented)
6. Select a terminal tab again
7. Use cmd+delete to delete the terminal (this time it will stop working)

Expected Behavior

The terminal should be deleted.
