fix(fabric): deploy contract go bin endpoint test

[petermetz]

Describe the bug

Test that deploys go binary contract fails on TravisCI but succeeds locally.

To Reproduce

It is not clear how this can be reproduced because the test appears to be a flaky one.
The test that is seen failing on the linked logs have been running successfully for some time and it still does for the most part.

Expected behavior

Test should not be flaky, either always pass or always fail.
