[sources] Skip problematic sources when starting shell instead of crashing. Closes #3670208
At least this gives an opportunity to fix the problem in using c-c shell, which
is currently not possible because it crashes during initialization.
Notice that since sources are copy based, it should not be a problem at all to
have some disabled, beside for services such as authentication sources as
ldapfeed.

Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
