Quick Edit link doesn't generate correctly if machine name has test in the beginning

Problem/Motivation

Quick Edit link doesn't generate correctly for Results, Build and Settings buttons if a Webform machine name begin with "test".

Steps to reproduce

1. Install/Enable Webform and Quick Edit
2. Create Webform with Title "Test Case Issue Form" should have machine name (test_case_issue_form) and add any elements
3. View Webform "Test Case Issue Form" (/form/test-case-issue-form)
4. Note the quick edit button shows 4 links
   • Test (/form/test-case-issue-form?_webform_test=test_case_issue_form)
   • Results (/form/test-case-issue-form?_webform_test=manage)
   • Build (/form/test-case-issue-form?_webform_test=manage)
   • Settings (/form/test-case-issue-form?_webform_test=manage)

Proposed resolution

Improve regex to check for /test at end of the URL string within webform.contextual.js. Adding End of String character ($) resolves this issue patch is attached.
