Remove CtsThemeHostTestCases from general-tests suite

The test is not used in TEST_MAPPING. Removing it from genera-tests
suite allows:
1. Reduce size of general-tests.zip
2. Reduce sandbox setup time (the test contains a 120MB jar file that
requires to be staged before sandbox process starts. This is unnecessary
as the test is not part of Test Mapping suite.

One shall add the suite back if the test will be part of Test Mapping.
