Subject: [PATCH] Fix query string parsing bug.

With some specially-formatted URLs, query strings would be sent to
the server even when they didn't exist.  This has been corrected by
not only checking for $null, but for string length.  Surprisingly,
I wasn't able to reproduce this on all versions of PowerShell that
this module supports.
