Deleted and Missing assets not showing in the Submit to Source Control window

[SRombauts]

The recent refactor of UpdateStatus() broke this feature.

Special case for "status" of a directory: requires a specific parse logic (this is triggered by the "Submit to Source Control" top menu button) :

We now search recursively all files in the directory: this enable getting the list of "Controlled" (unchanged) assets, but this cannot detect assets removed / locally deleted (they are no files left to find!)
