Subject: url: normalize CURLINFO_EFFECTIVE_URL

The URL extracted with CURLINFO_EFFECTIVE_URL was returned as given as
input in most cases, which made it not get a scheme prefixed like before
if the URL was given without one, and it didn't remove dotdot sequences
etc.

Added test case 1907 to verify that this now works as intended and as
before 7.62.0.

Regression introduced in 7.62.0

Reported-by: Christophe Dervieux
Fixes #4491
Closes #4493
