[camera] Skip another flaky Android test

[stuartmorgan]

This test is showing the same flake as the recently-skipped "detached create does not call create on the Java side" tests.

See flutter/flutter#164132

Hm, I just had to re-run a different test that flaked with the same PlatformException(channel-error, Unable to establish connection on channel., null, null). Maybe this is a structural problem with the version of the proxy code it's currently using?

LGTM

The method call fails asynchronously, so its probably possible that it depends on if the machine finishes all the tests before the failure happens.

I may need to disable all of these tests then, because now the next test is failing all the time (maybe because it's a shorter test run)
