Wrong set_lang call in reports

The calls to set_lang has been on a single line in most report template (I think it is by #6011 (closed)). This makes them not being called because the last statement erase of the line erases the all lines.
relatorio control statements should always be put on a single line.
I propose to fix it after #6545 (closed) to get a reviewable patch.

Indeed it comes from #4904 (closed)

Indeed I think the right thing to do is to use the new 'replace' directive from relatorio 0.6.2. Like that, the empty line will be removed.
So the statement will be:

replace text:p="set_lang(…) and record.set_lang(…) and ''"

Indeed we can not chain the calls like that because the first set_lang returns None and so the other will not be called.
Instead I think we must add a line for each call:

replace text:p="set_lang(…)"
replace text:p="record.set_lang(…)"
