[SearchHelper, DSP] Removed a bunch of confusing EnsureResultSource overloads.
- We gotta hide implementation details better and present a simpler interface on our helpers
- SearchHelper will need to be split up into ResultSourceHelper, ResultTypeHelper, etc. because it's becoming bloated.
- Removed old unused solution file and stylecop file
- DSP: Site collection creation doesn't write Verbose traces for Content Database creation anymore, less spammy
