[Rails5.2] Bump database_cleaner gem
The current version 1.5.3 of database_cleaner
does not support rails5.2 (didn't check, but maybe even rails5.1)
https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/135978879 (rails5.2 branch)
An error occurred in a `before(:suite)` hook.
Failure/Error: DatabaseCleaner.clean_with(:truncation)
NoMethodError:
undefined method `schema_migrations_table_name' for ActiveRecord::Migrator:Class
# ./spec/support/db_cleaner.rb:20:in `block (2 levels) in <top (required)>'
Quick test of bumping the gem to the latest stable version in that branch showed that that solved the problem.
