VARCHAR requires a length on dialect mysql

[soulee-dev]

Hello

Problem

There is something error on creating tables on MySQL.
sqlalchemy.exc.CompileError: (in table 'user', column 'email'): VARCHAR requires a length on dialect mysql
effected columns
SQLAlchemyBaseUserTable:
email
hashed_password

SQLAlchemyBaseOAuthAccountTable:
oauth_name
access_token
refresh_token
account_id
account_email

According to SQLAlchemy Docs,
CREATE TABLE DDL is issued if a VARCHAR with no length is included.

Solution

Pull request #344

I think the best way of solve this problem is adding length to columns.
