Create atoms template check

[S-Lykles]

Summary
This adds a check in create_atoms to ensure that if atom_style template is used, the same molecule template is used in the atom style as in the create_atoms command. I saw that this check is already performed in fix pour and fix deposit, but not yet in create_atoms.
