fix(test): pass accountRepository to DiagnosticsCollector in CrashReporterInstallTest

DiagnosticsCollector gained a 4th constructor param (accountRepository) for the
PII-free account summary, but CrashReporterInstallTest still constructed it with
3 args — a compile error that broke the Unit tests and Static analysis gates.
Add the AccountRepository mock with observeAccounts() stubbed to an empty flow
(matching DiagnosticsCollectorTest) and pass it to both call sites.
