libproj: fix area bbox for PROJ

[metzm]

The PJ_AREA has not been properly estimated. As a result, sometimes the wrong PROJ pipeline was chosen, or PROJ failed to find a pipeline at all.

This also fixes a segmentation fault in v.proj with --verbose reported by valgrind as:

==825924== Conditional jump or move depends on uninitialised value(s)
==825924==    at 0x4857D5E: pj_print_proj_params (get_proj.c:538)
==825924==    by 0x10B32C: main (main.c:205)

The fix is the move of the following lines (info_in was not initialized):

if (G_verbose() == G_verbose_max()) {
    pj_print_proj_params(&info_in, &info_out);
}

Thanks!

Workaround is (before 8.2.1 and/or 8.3.0): Don't use verbose mode with v.proj or with whatever calls v.proj (notably, r.import and v.import).
