Relating to a Werkzueg issue (pallets/werkzeug#2691), when parsing an iOS App install url e.g.
itms-services:action=download-manifest&url=https://theacmeinc.com/abcdefeg, urlunpslit returns an invalid url.

e.g.

vals = urlparse( "itms-services://?action=download-manifest&url=https://theacmeinc.com/abcdefeg" )
print(vals)
newURL = urlunsplit((vals.scheme, vals.netloc, vals.path, vals.query, vals.params))
print( newURL )

prints:

ParseResult(scheme='itms-services', netloc='', path='', params='', query='action=download-manifest&url=https://theacmeinc.com/abcdefeg', fragment='')
itms-services:?action=download-manifest&url=https://theacmeinc.com/abcdefeg

Note the newURL is missing the // after the itms-services scheme.

This scheme is used to install ad-hoc and enterprise iOS apps.
