Filtering on special chars sends back an un-escaped special character in the links urls

[ScottEDubya]

Description

When filtering on a special character, the links sent back don't use the encoded characters.
e.g. a GET request to look for a name of "&" /entities?filter[name]=%26 responds with incorrect urls in the links object:
(expected):

"links": {
        "last": "http://localhost:54168/entities?page[size]=50&page[number]=1&filter[name]=%26"
},

(actual):

"links": {
        "last": "http://localhost:54168/entities?page[size]=50&page[number]=1&filter[name]=&"
},

Environment

• JsonApiDotNetCore Version: 2.4.0
• Other Relevant Package Versions: n/a?
