Better handle access to the interface when no "seeker" account is created

[maaaaz]

Hello,

Trying to access the interface when no seeker account is created leads to the following error:

sqlalchemy.exc.OperationalError

OperationalError: (sqlite3.OperationalError) no such table: users [SQL: u'SELECT users.id AS users_id, users.username AS users_username, users.password AS users_password, users.email AS users_email, users.active AS users_active, users.encrypted_master_key AS users_encrypted_master_key, users.b64_kdf_salt AS users_b64_kdf_salt \nFROM users \nWHERE users.username = ?\n LIMIT ? OFFSET ?'] [parameters: (u'seeker', 1, 0)]

Please handle better that case providing a nice error message :)

Cheers.
