This partilaly reverts commit 5e18ff208a.
It leaves the compilation fix that was made to
BinderClientTransportTest.
Running instrumentation tests via firebase requires a `--app` argument.
However, we don't have such an app and it isn't immediately clear how
we'll go about making one. Revert the change to let android-testing to
start passing again.
This problem wasn't noticed before merging the original commit because
android-testing is a post-commit CI.
