Limit queries to nevra forms when provided by command

Command `dnf install-n <provide>` does not install only according
to package mame but still search in provides. The patch limits
searrch only to NEVRA forms for install, remove, autoremove,
and repoquery commands.

Resolves partially: https://issues.redhat.com/browse/RHEL-5747
