bridge. compiler has issues with files deleted outside bridge.

[Chikorita-Lover]

Summary
Deleting a file in a bridge. project outside of bridge. (e.g. via File Explorer or GitHub Desktop) trips up bridge.'s compiler. bridge.'s compiler will throw an error saying it can't find the file, and will prevent the project from compiling, requiring bridge. to be refreshed. This can be fixed by restarting watch mode.

To Reproduce
Steps to reproduce the behavior:

1. Open an external file manager (e.g. File Explorer)
2. Delete a file in a project
3. Compile the project (e.g. by editing a custom command)
4. Observe result

Observed behavior
Compiling the project will throw and error and stop compiling
Expected behavior
Deleting the file should not cause any errors with compiling

Platform (please complete the following information):

• OS: Windows 10
• App Version: 2.2.11

Additional context
This occurred for me after deleting a function through GitHub Desktop and attempting to save a custom command. The compiling would be stopped after throwing an error, saying the deleted file was not found.
