Rename RegressionTests to RenderTests

The tests that used rendering and image comparison were named
`RegressionTest*`. However, this name is not very descriptive as all the
tests are regression tests. These have all been renamed to be
`RenderTest*` to more clearly indicate that they are tests that use
rendering as part of the test.
