Fix flaky test in releases_controller_spec.rb
Multiple release objects would be created in the test with the same tag
(v1.1.0), which caused random failures, depending on what the database
returned for Releases.find_by_tag!
. Since there is no uniqueness
constraint, we fix this problem by turning the tag
field into a
sequence.
Closes #37372 (closed)
