Environment variable template (<<foo>>) appears urlencoded (%3C%3Cfoo%3E%3E)

[zahhar]

Describe the bug
When a request used from Collection has environment variable interpolated into its URL, that variable appears urlencoded ("<" char replaced with "%3C" and ">" char replaced with "%3E"). No impact on functionality: interpolated variable still works, just looks ugly in URL field.

To Reproduce

1. Define pre-request environment variable: pw.env.set('foo', 'bar');
2. Use it in your request URL: example.com/<<foo>>
3. Save request to collection
4. Click on same request in collection to populate it into the form
5. You will see that instead of expected example.com/<<foo>> URL field contains example.com/ %3C%3Cfoo%3E%3E.

Expected behavior
When using request from Collection its interpolated variables should appear same as they were saved, without urlencoding template.
