require bundler in bug_report_templates_test

fix #1013
fails when rake runs without bundle exec

Does this prevent all the output that happens when you require 'bundler'? When I put "require 'bundler'" i got all this output, but could just be me:

add optional log silencer

@lgebhardt take a look, please

@senid231 This looks fine, though I'd be just as happy excluding the test from being run. That could be done by removing assert_bug_report 'rails_5_master.rb' from test/bug_report_templates_test.rb.

Do you see any reason to run the bug_report_templates as part of standard testing?

[senid231]

I think we need to be sure that bug report template works for master. But adding it to test suite looks little ugly. It will be better to create separate rake task for it and run after test suite.
@lgebhardt do you agree with this?

[lgebhardt]

@senid231 That sounds right.

[senid231]

reworked and rebased
rake task for bug report template added and used on default rake

@lgebhardt, please take a look

@senid231 Thanks for cleaning that up. I've merged it as is, but I do wonder if we should exclude the new task from the default rake. But we can do that later if it causes problems.
