BUG/MAJOR: http: fix buffer overflow on loguri buffer.

The pool used to log the uri was created with a size of 0 because the
configuration and 'tune.http.logurilen' were parsed too earlier.

The fix consist to postpone the pool_create as it is done for
cookie captures.

Regression introduced with 'MINOR: log: Add logurilen tunable'
