public static function Uri::composeComponents in Auth0 Single Sign On 8.2

Composes a URI reference string from its various components.

Usually this method does not need to be called manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.

PSR-7 UriInterface treats an empty component the same as a missing component as getQuery(), getFragment() etc. always return a string. This explains the slight difference to RFC 3986 Section 5.3.

Another adjustment is that the authority separator is added even when the authority is missing/empty for the "file" scheme. This is because PHP stream functions like `file_get_contents` only work with `file:///myfile` but not with `file:/myfile` although they are equivalent according to RFC 3986. But `file:///` is the more common syntax for the file scheme anyway (Chrome for example redirects to that format).
