Describe the bug
Query parameters when added to a request are appended without trimming white space and are not URL encoded.

To Reproduce
Steps to reproduce the behaviour:

Start a new GET request.
Click on the parameters tab.
Add a parameter key and value of type Query with white space or a space between two words.

e.g:

Parameter: Lorem Ipsum
Value: Dolor Amet

Review the parameters appended to the request URL. The parameters are NOT URL encoded and all white space is still visible and unchanged.

Expected behaviour

Query parameters should be URL encoded, resulting in white space being trimmed & special characters being replaced with the relevant UTF8 encoding of the relevant character.

The space character is excluded because significant spaces may disappear and insignificant spaces may be introduced when URI are transcribed or typeset or subjected to the treatment of word- processing programs. Whitespace is also used to delimit URI in many contexts.

From RFC 2936, section 2.4.3:

The space character is excluded because significant spaces may disappear and insignificant spaces may be introduced when URI are transcribed or typeset or subjected to the treatment of word- processing programs. Whitespace is also used to delimit URI in many contexts.
