Crucible review dysfunctional when file path contains apostrophe character

Summary

1. Symptom 1: After the upgrade, for an existing review screen, it shows the files, but when a file is clicked, it doesn't show the source for the file. Trying to summarise or close the review will also fail.
2. Symptom 2: When creating a new review, the wizard does not show the screen for picking the reviewers. It skips that screen and instead creates the review in a draft mode.

Steps to Reproduce

1. Create a directory in your SVN repository with name having an apostrophe.
2. Add a file under that directory and checkin the directory and file into SVN.
3. Create a review for this changeset

Expected Results

The Review can be edited and created successfully.

Actual Results

When creating review for a changeset, the edit review dialog doesn't show and JS errors are reported on this action:

Edit action fails with error:

URL: /foo/json/cru/edit-details
404: Not Found

The exception reported is:
