Swallow exceptions in TestContentProvider when writing to a pipe fails

Browse Source 
The existing code results in flaky tests, where sometimes the write
fails (with "EPIPE (broken pipe)") and the exception propagates out
and causes the test to never complete and time out.

Swallowing the exception resolves this flakiness.
