BUG/MEDIUM: httpclient/cli: free of unallocated hc->req.uri

httpclient_new() sets the hc->req.uri ist without duplicating its
memory, which is a problem since the string in the ist could be
inaccessible at some point. The API was made to use a ist which was
allocated dynamically, but httpclient_new() didn't do that, which result
in a crash when calling istfree().

This patch fixes the problem by doing an istdup()

Fix issue #1452.
