This fixes a bug where a re-import of the contacts directory failed
because some entries already exist.
With this change, one can import the contact directory after things
changed in there and the imag database is updated accordingly, but not
altered. So links and notes are persisting.
For completeness: before, the workflow was to
`cd $IMAG_RTP && git rm store/contacts -r && imag contact import /path/to/contacts`
which is of course not optimal.

This reverts commit b90abfb868.
Because `libimagcontact` is not based on `libimagentryref` anymore (as
of 2b10ab0b36), and thus does not put
pathes into the header, we can allow non-absolute pathes here.
The complexity of the create() routine justifies the move to another file.
This commit implements the create() functionality which creates a TOML
tempfile which the user should edit and then reads the contents to build
the Vcard object which then gets written to either stdout or the
destination file.
Besides that:
* Move helper function to util module
* Rewrite and fix tests
* Implement contact listing with formatting via commandline or config
* Implement importer functionality for contact
* Implement "show" subcommand
* imagrc.toml: Add explanation which fns are supported in templates
