2015.8.7 pkg.installed fails using version if epoch is set.

[stepherg]

Trying to move from 2015.5.5-1 to 2015.8.7-1, I found the following issue:

Installing RPMs by version that have an 'epoch' set (like sensu) report install failure apparently because the version returned by parse_pkginfo() is prepending the epoch to the version that's used by _verify_install(). Although the installation actually succeeds, it causes problems with other states that have the install as a dependency.

I edited my local version of rpm.py to remove the addition of the 'epoch' field to the version and the installation worked as expected. Would it be safe to do this as a fix or will that create other issues? Is this a known problem in this version?

Thank you.
