Subject: [PATCH] Skip rich deps for autodetection of unmet dependencies

Rich dependencies are difficult to properly evaluate because we do not
have enough information about past and only libsolv is capable to
evaluate it in comparison to present state of the system.

Additionally - rich deps are used for langpacks therefore disabling
unmet rich deps will have a negative impact on UX.
