Fix several issues related to relative paths when creating a new project

[pascalw]

• CLI now resolves relative paths into absolute paths

• This still didn't cut it for projects created with the init script, since the init script called the Maji CLI from a temp directory. This isn't nessecary, so the init script now invokes the Maji CLI from the original PWD where the init script was ran.

• Last, some additional logging was added and output of git init is supressed to remove some noise.

Maybe add a fix for https://github.com/kabisa/maji/issues/179 as well? 😁
