[BUG] `mojo package .` creates `..mojopkg` instead of `$BASENAME.mojopkg`

[ucirello]

Bug description

Actual behavior

mojo package . creates a dot-name file.

Expected behavior

I expected that mojo package . to behave the same as mojo package $PWD

Steps to reproduce

$ mojo package .
$ ls *.mojopkg
ls: *.mojopkg: No such file or directory
$ ls *mojopkg
ls: *mojopkg: No such file or directory
$ ls .*mojopkg
..mojopkg

vs

$ mojo package $PWD
$ ls -lah *mojopkg
nanoid.mojopkg
