Feature request: improve error message when Espresso Intent matching fails due to mismatched Intent data

[stkent]

When Espresso Intent-matching fails to find a matching intent, it prints an error message:

android-test/espresso/intents/java/androidx/test/espresso/intent/VerificationModes.java

Lines 56 to 57 in f7d881a

	"Found unverified intents.\n\nUnverified intents:%s\n\nRecorded intents:%s",
	joinOnDash(unverifiedIntents), joinOnDash(recordedIntents)));

that includes string representations of all expected Intents and all recorded Intents.

Currently, this error message obfuscates the data associated with each Intent, because ResolvedIntentImpl::toString:

android-test/espresso/intents/java/androidx/test/espresso/intent/ResolvedIntentImpl.java

Line 57 in f7d881a

"%s handling packages:[%s]", super.toString(), getPossibleResolutionPackages()));

relies on Intent::toString rather than Intent::toInsecureString.

This makes debugging difficult if the reason for the Intent matching failure is a discrepancy in Intent data. Ideally, ResolvedIntentImpl::toString would use Intent::toInsecureString rather than Intent::toString, but I don't know how feasible that is.
