With contractions, the apostrophe (') replaces a missing vowel:
EX:
It is => It's
The sound represented by the letter "h" is a puff of air, and so it's often dropped:
EX:
It has => It _as => It's
The sound represented by the letter "w" requires a great deal of articulation: rounded lips, vibrating vocal folds, raised tongue height, so it's never dropped:
EX: It
was => It
was
In short,
It was cannot contract to
It's beacuse "w" is in the way.
