Update migration script to test run warnings

When running the entire test suite, many warnings would be output:

/Users/bw/Projects/gollum/test/test_migrate.rb:37: warning: already initialized constant HYPHENATE
/Users/bw/Projects/gollum/test/test_migrate.rb:37: warning: previous definition of HYPHENATE was here

/Users/bw/Projects/gollum/bin/gollum-migrate-tags:236: warning: already initialized constant TREE
/Users/bw/Projects/gollum/bin/gollum-migrate-tags:236: warning: previous definition of TREE was here

While it's unlikely that end users would ever see these warnings, as
they'd only be running the migration script once, they will always be
shown in our local test runs and CI run output.

So instead of using constants in our migration script, I change the
script to use class variables instead. This should not effect the
functionality of the migration script whatsoever.
