Reland: Fix DexLoaderTest#testLoadAfterDeleteCachedDexes() flakiness part 2/2

There seems to be data cached by the OS which is not deleted by
DexLoader#deleteCachedDexes() which is causing the test to be flaky.
This CL changes DexLoaderTest#testLoadAfterDeleteCachedDexes() to test
DexLoader#deleteCachedDexes() in a scenario which is closer to how the function
is used in production.

The test used to test that calling DexLoader#deleteCachedDexes() would make
DexLoader#load() load a dex file from scratch.

The CL changes the test to test that:
- DexLoader#deleteCachedDexes() deletes previously extracted dexes from the local
data directory
- It is possible to use reuse a data directory to load several dexes
