[autotest/intergration] Wait for pointer enter before simulating button press

The test LockScreenTest::testPointerButton and testPointerAxis both
fail on Neon's CI infrastructure. In order to make the test more reliable
the tests first wait for the pointer enter after unlock before simulating
another button press.
