Fix db create error in MySQL

  - MySQL needs fixed lengths in VARCHAR datatypes. Fixing code to have that
    for MySQL.

 # Import all modules which represents a SQLAlchemy model;
 # they have corresponding tables that are needed to be created

 from swtstore.classes.models.um import User, Group, Membership
 # Create them!
 db.create_all()
+if __name__ == '__main__':
+    # Create them!
+    db.create_all()

     context_id = db.Column(db.Integer, db.ForeignKey('contexts.id'))
     what = db.relationship('Context')
     where = db.Column(db.String, nullable=False)
+    where = db.Column(db.UnicodeText, nullable=False)
     how = db.Column(JSONType)

     similarly, convert string to dict while loading from database
