Fix a bug in justify-self parsing where in auto | normal | stretch | <baseline-position> | <overflow-position>? [ <self-position> | left | right ]

the <overflow-position> [left | right] and <self-position> parsing were missing.
Fixed a bug where delegating parsing of the justify-self part forgot first extra value before parsing -> recreate a new expression before proceeding.

This should fix #338
