Subject: [PATCH] Add some tests for IsCheckingBuffer

Adding a couple of tests to demonstrate how IsCheckingBuffer behaves
during specific autocommand hooks:

* At ALELintPre, no linters have actually executed yet, hence
IsCheckingBuffer should be returning false.
* ALEJobStarted, fires as early as reasonably possible after a job has
successfully started, and hence hooking into IsCheckingBuffer here
should return true.

This distinction is important when using these two events during things
like statusline refreshes, namely for "linter running" indicators.
