Removed disabled ticker test suite (no longer needed).

Removed disabled ticker test suite (no longer needed).

The tickers test suite is disabled. In addition, most tests there are broken.
Date ticker tests are fixed and moved to a separated date ticker test suite
by last commit. Hence move numeric ticker tests to the numeric ticker
test-suite and remove the disabled tickers test-suite.

  * `auto_tests/tests/numeric_ticker.js`:
    Include tests from `auto_tests/tests/tickers.disabled-js`
    but commented because they are all broken.

  * auto_tests/tests/tickers.disabled-js:
    Delete it because it is no longer needed.
