Don’t adjust time column widths in cf_open
The time column widths should not be adjusted in cf_open() because
we don’t have any packets yet and Qt resizeColumnToContents() will
not adjust any widths but emits a sectionResized() with invalid or
default values (new_width seems to always be 32). This will in some
cases (when start capturing packets) give wrong width values which
is later stored in the recent file, and the time columns may end up
narrow the next time the recent file is read.
This fix is related to the column with issues previously compensated
for in PacketList::sectionResized() (g4980d505).
