Fix the wrong package name to return the wrong resources.

It should pass mSuspendingPackage instead of mSuspendedPackage as the
parameter of the getResourcesForApplication.

Root cause: The intellij is very smart to provide the autocomplete
    options and the developer choose the wrong option.
Solution:
    * Add file_pattern in TEST_MAPPING to trigger the CTS tests.
    * The developer should take the autocomplete option very
      carefully especially the options are very alike.
