fix(base): source hooks without exec

Patch 2fabaaa changed the behaviour for `dash`
under the assumption, that dash does not take parameters for `.` aka
`source`. Although this is true, the original positional parameters of
the `source_all` function are still in place, so everything is
fine with the old way of sourcing.
