[FIX] web: show page number in report

Following 4a3fd02 on the portal when displaying an invoice we may get
a report_type variable (with value 'html' or 'pdf') on the portal.

This was used to not display the page number when checking the report,
but when the report is printed in the backend this report_type was unset
so the page number was mistakenly removed too.

With this changeset, the report alway know if he is pdf, html or text
and only print the page number if it is of type pdf.
