solver: fix potential install_if processing failure, fixes #8237

In discovery phase, there was logic to not process packages
multiple times. However, that logic failed to account the package's
depth and install_if state for the name being processed. This
caused install_if processing failure in certain topologies of the
dependency graph. Adds also a test case that should catch this
issue reliably.
