Subject: [PATCH] Fix deprecation warnings (#417)

* Fix Nokogiri deprecation warning

Nokogiri warning:

```
warning: Passing a Node as the second parameter to Node.new is deprecated. Please pass a Document instead, or prefer an alternative constructor like Node#add_child. This will become an error in a future release of Nokogiri.
```

Please see the following for more details:
https://github.com/sparklemotion/nokogiri/issues/975

* Require 'mocha/test_unit' instead of 'mocha/setup'

Suppress the following deprecation warning:

```
Mocha deprecation warning at /home/runner/work/gollum-lib/gollum-lib/test/helper.rb:9:in `require': Require 'mocha/test_unit', 'mocha/minitest' or 'mocha/api' instead of 'mocha/setup'.
```
