Property for splitting paths

[ThomasArts]

This QuickCheck property verifies that the URIs provided are split path correctly.

Given the quoting and %-encoding rules that apply this is not totally trivial and earlier versions did spot a few mistakes in the code.

We generate both valid and invalid URIs and verify that when an error is produced, the URI generated is indeed invalid. For valid URIs the path should split correctly.

All parameters should decode as tuples.

The test needs to support OTP 26/28:

test/uri_eqc.erl:
    │
 56 │                      [{params, equals(Params, maps:get(query, URIMap, []))} || maps:get(query, URIMap, []) /= [{~"", true}] ]
    │                                                                                                                 ╰── syntax error before: '~'

     ┌─ test/uri_eqc.erl:
     │
 136 │  mk_path(_, []) -> ~"";
     │                    ╰── syntax error before: '~'

...

Is this an OTP 26 support issue?
