debug: fix disabling breakpoints

[vince-fugnitto]

What it does

Fixes: #8222

The following pull-request fixes an issue where attempting to disable breakpoints during an active debug session would remove the breakpoint rather than disabling it. The fix includes updating the clause which controls whether debug breakpoints should be updated (removed).

How to test

1. start the application with theia as a workspace
2. open a *.spec.ts file (ex: cli.spec.ts)
3. add a breakpoint(s) in the editor
4. open the debug-view
5. confirm through the debug view that the breakpoint can be disabled/enabled (through the checkbox)
6. select the run mocha tests debug configuration
7. confirm that once the debug session hits the breakpoint, step 5 works
8. confirm that disabling all breakpoints still works
9. confirm that removing all breakpoints still works

The following does not work yet when multiple breakpoints are present when starting a debug session.
