Maya: Use project name instead of project code

[iLLiCiTiT]

Brief description

Use project name for root preparation instead of project code.

Description

Using project code can cause that anatomy won't be created for right project so root values will be invalid.

Testing notes:

1. Loading in Maya should work

Testing notes:

• This would only be relevant when testing with project settings enabled for maya.maya-dirmap.use_env_var_as_root.

Reference Loaders work, reopening and resolving works too.
