Bug 1580554 - Move common report test cases into head_abuse_report.js and run them on sub-frame and dialog mode. r=mstriemer

Move test helpers and the common abuse report test cases (the ones that should run in sub-frame and dialog window mode)
into an head_abuse_report.js support file, then run all the common test cases from browser_html_abuse_report.js
(in sub-frame mode) and browser_html_abuse_report_dialog.js (in dialog window mode).
