[Xsltforms-support] Xsltforms minor fix

[Javier D. <jd...@tc...>]

Hello,

another change (i don't know if it is a better way to share this than
using this maillist).

When a get submission is done where instance parameters are passed in
url, if xsltforms instance is empty (because form is still empty), no
data is appended to url but the separator is always included at the end
of url.

It is necessary to validate if there is any data to avoid include the
separator when it isn't needed:
