CtsAppCompatHostTestCases:operate:After issuing the command to uninstall the application, increase the waiting time to ensure that the value obtained during assertion is correct.

In method assertThat(ctsChange.hasRawOverrides).isFalse() of AppCompatOverridesServiceTest.java,
Due to the low performance of the MT6762 chip platform, uninstalling applications takes a longer time compared to other high-performance platform chips,
and it is not possible to update the value of ctsChange.hasRawOverrides before asserting.
This results in ctsChange.hasRawOverrides still being the value obtained during the installation of the testing application, leading to assertion failure.
After verification,increase the waiting time can ensure 100% pass of the test case.

failure message:
expected to be false
