Split the djblets.util.tests suites into per-suite files.
Review Request #9237 - Created Oct. 1, 2017 and submitted
djblets.util.tests was getting a bit large, and was only about to grow
larger with some upcoming changes. In order to keep things more sane,
this change splits the old tests file into a series of new files, and
moves the tests inside djblets.util.templatetags.tests into this
As many of these are from the early days of Djblets, most of these tests
were also using very outdated naming and styles. They've all been
updated for the modern style guidelines and to take advantage of modern
unit testing functions.
Unit tests pass.
Fixed an alignment issue.
