Addressable::URI interprets the `#` in a URI as a URI fragment
and does not escape it, but Rails has special helpers that treats
these as bona-fide characters that need to be escaped.

`Rugged::Reference.valid_name?` used in
`Gitlab::GitRefValidator.validate` fails on strings containing null
bytes because it uses `StringValueCStr()`. Per
https://silverhammermba.github.io/emberb/c/:

Ruby’s String kinda corresponds to C’s char*. The simplest macro is
StringValueCStr() which returns a null-terminated char* for a
String. The problem here is that a Ruby String might contain nulls - in
which case StringValueCStr() will raise an ArgumentError!

Upgrade better_errors gem to 2.5.0

See merge request gitlab-org/gitlab-ce!23312

After converting the test that verifies this partial's behavior from a
feature spec to a view spec, we're able to remove a few CSS classes that
were only used for scoping tests found in the feature spec. All the view
spec needs is the `have_link` matcher which allows us to check for a
specific `href` attribute.

A feature spec to test this simple behavior takes about 2 minutes to run
in CI. Everything it's testing is conditionals and `href` attributes,
which can easily be done in a view spec that runs in about 8 seconds.
