[Android Tests] Preload Calendar to avoid StrictMode violations

In instrumentation tests Calendar#getInstance can trigger ReadFromDisk
StrictMode violations when it needs to read system files to obtain the
time zone, which make tests fail. This patch preloads Calendar to avoid
it happening later on the UI Thread and avoid these flakes.

PTAL

Note: I could not repro the strict mode violation locally, even when removing
the property. Waiting to see if that removes the flakes from the bots:
