ANR due to PersistentIdentity#isFirstLaunch()

[mlu-pixum-com]

Dear Mixpanel Team,

We are experiencing ANR in our production application after we have updated to Mixpanel skd 8.2.0.
The previous ANR, which was in PersistentIdentity.getTimeEvents seems to be fixed.

The new one is in PersistentIdentity.isFirstLaunch:
