Analysis & Coverage section shows a wrong Test Status for the Test when filtering for Test Environments with characters like '+'

Short Description: Analysis & Coverage section shows a wrong Test Status for the Test when filtering for Test Environments with characters like "+".

Steps to Reproduce:
1 - Create a Story.
2 - Create a Test under the Story.
3 - Create a Test Execution with an Env that contains "+" and pass the test run.
4 - Go the Story and filter the Test Env for that one.

Actual Results: The test status is not retrieved correctly and therefor the coverage is wrong.
Expected Results: The test status should be retrieved correctly.

Some characters maybe are messing up the request, which contains a similar character. I also, tried with "&", "/", "?", "=" or "_" and it worked ok.
