bug#66183: elixir-ts-mode test failure

[john muhl]

The change in 5cba5ee8905 caused an elixir test to start failing. The
white space at the start of the test is now in a heex range so pressing
tab there matches a heex rule instead of the elixir one. Moving the
dummy range to the end fixes the test.
