rofi-pass: honor default_autotype in config

The file "analyzer" was checking whether the pass file contained an
"autotype" field: if it did, it would do nothing; and if it didn't, then
it would use a hardcoded "autotype" value (user :tab pass).

This caused issues down the line because the code that would use the
config's values would always find an existing "autotype" value (whether
hardcoded in rofi-pass or supplied by the pass file), and would never be
able to apply the settings from the config file.

I would suggest (re)-using the fields ("autotype" in that case) with
values in order of preference; but for the moment, this patch does the
job.

1. autotype="user :tab pass" # hardcoded
2. if config exists and supplies it, then autotype="whatever is in
   config"
3. if the pass file supplies it, then autotype="whatever is in pass
   file"

Fixes carnager#227
