PhabricatorApplicationTransactionEditor: fix empty style="" attribute, fix unuseful implode() call
Summary:
May 18 2016, 23:16, a style="..." attribute was introduced with a single style rule:

May 20 2016, 20:52, that style rule was removed, causing empty HTML attribute style, and unnecessary implode() call:

So, we drop this empty HTML attribute.
Test Plan: Look at the code.
