gitlab-ci: force skip Espresso tests on < android-25

It seems that ARM emulators timeout even when just trying to run the
assumeTrue() tests via Espresso.  There needs to be one test still enabled
in the file, otherwise, the run fails with:

org.fdroid.fdroid.MainActivityEspressoTest > initializationError[Nexus_One_API_19(AVD) - 4.4.2] FAILED
        java.lang.Exception: No runnable methods
        at org.junit.runners.BlockJUnit4ClassRunner.validateInstanceMethods(BlockJUnit4ClassRunner.java:191)
