system_resolver is created based on loaded configuration, which could
avoid calls like `GenericResolver.create(conf)` repeatedly in the code.
However, if some cases need to create a specific resolver explicitly,
`GenericResolver.create` could be called with addition argument, for
example db or mbs is passed to argument backend in tests.

During I'm reading through the code base to learn MBS, I found out some
typos and minor issues in some other docstrings, and I also found some
docstrings with extra informative description could make it easier to
understand the code.

This bug was reported by @nphilipp here https://bodhi.fedoraproject.org/updates/FEDORA-2018-c9c3a37d96
The issue is that the `record_filtered_rpms` method returns a new xmd
buildrequires block, but whole buildrequires entries were omitted in the return
value for local builds. This one-liner includes them again.
This reverts commit 8173040ea6. Since it didn't
provide any real benefit after talking with sgallagh, it seems like we'd better
off not introduce more risk to the next deployment.
MBS has been using the libmodulemd API incorrectly by assuming that
methods like `get_rpm_components` return the actual object in memory
and not a copy. This has been true but wasn't something sgallagh
intended. We found this out after he had me test his new version of
libmodulemd. This PR removes those assumptions.
1. Changed ModuleBuild's context property to db column, it's
non-nullable and default value is '00000000' to keep it consistent
with previous behaviour.
2. Changed ModuleBuild.contexts_from_mmd to return a tuple of
(ref_build_context, build_context, runtime_context, context).
3. Updated tests affected by this change.
