mobile/edit: don't add dive site twice to table

When editing a dive on mobile we might have to create a new
dive site. That site is added to the global dive site table
in the undo command. However, the code in QMLManager created
the dive site with create_dive_site*() functions, which already
adds it to the table. The undo command then added the dive
site again leading to a hang of the application.

To solve this problem, create new alloc_dive_site*()
functions that do the same as create_dive_site*()
but do not add it to the table.
