gource: update patch comment
Only mark install as attempted if it was actually attempted

Commit 30a08f5cc707 ("Don't attempt installation multiple times") was
correct in raising FormulaInstallationAlreadyAttemptedError early enough
to prevent the other exceptions in #check_install_sanity from being
raised, but it should not have moved the point at which formulae are
added to the attempted set. Doing so prevents the installer from being
instantiated multiple times on the same formula, even if installation
was never attempted.

Put it back where it belongs.

Remove <=> from Dependency interface

It is important that dep equality corresponds to the name attribute, but
we may want to use the Comparable interface to sort them by installation
order in the future. Code that needs to sort them alphabetically should
just use sort_by.
Split up dependency test coverage

The DependencyCollector tests are really integration tests, while the
rest are closer to real unit tests. Split them up so that the tests can
be run in isolation on a per-class basis.
