- revert partly fix which broke test of @select in route script. - leave the correction for seg. fault on @select match against regexp.

- the comp_select and the select's itself need to be reviewed (I don't expect it will be done in 2.0)
= the select was created so it returns 1 if empty string, now it would be nice to return 1 for N/A values
and 0 (res.len=0) for empty strings
= now we need to ditinguish of N/A, empty and some value (e.g. for SIP request's header parameters)
= affects how the test is used in ser.cfg, so the example script will have to be reviewed too
(if (@to.tag=="") can't be true, as the tag MUST have value if present)
