aurman: Solver doesn't check versioning of repo providers correctly

aurman r257.f2ce5f5-1.

My system is fully up-to-date, and reinstalling a random AUR packages seem to requier removal of unrelated repo packages:

$ aurman -S pacaur-git

~~ analyzing installed packages...
~~ fetching upstream repo packages...
~~ fetching needed aur packages...
~~ fetching ignored packages...
~~ calculating solutions...

:: The following 2 package(s) are getting removed:
   community/intellij-idea-community-edition  2:2017.3.4-1          ->  /
   extra/jdk9-openjdk                         9.0.4.u11-1           ->  /

:: The following 1 package(s) are getting updated:
   aur/pacaur-git                             4.7.10.47.ga0f232d-1  ->  4.7.10-1
?? Do you want to continue? Y/n: n

The issue seems related to versioned providers. jdk9-openjdk provides java-environment=9, while intellij-idea-community-edition depends on java-environment. As a side note, the package jre8-openjdk, providing java-runtime=8, is also installed (though it shouldn’t matter here I guess).

With --deep_search, other repo packages need to be reinstalled for some reason:

$ aurman -S pacaur-git --deep_search

Maybe that list of “reinstalled but actually not reinstalled” packages shouldn’t be printed, unless it is actually useful in some way to the user(?)
