encoding longUrl for admin-ajax.php breaks some urls

[adamcoulombe]

Some long urls that contain spaces like %20 (or other encoded data) are not being saved to the DB faithfully.

take the following url for example:
https://mydocumentsharingplace.net/My%20Storage%20Folder/My%20Shared%20File.txt

gets stored in the shlink database as:
https://mydocumentsharingplace.net/MyStorageFolder/MySharedFile.txt

Which results in being redirected to a 404, because it isnt the same URL.

I suspect the issue is that the longUrl is being encoded and passed as a URI argument through admin-ajax.php as opposed to being sent in the request body as JSON. When I test the same URL using the Shlink web app, the URL is saved in the DB correctly. The shlink webapp accesses the shlink rest API directly.

I should note that I tried decoding the url before encoding it, which sort of worked for some URLs, but created other issues for other URLs
