SpeckleCache.db allows duplicate account entries

• I've read the contribution guidelines!

Expected Behaviour

Logging in with the same email and server as an existing user account should not be possible.

Actual Behaviour

It is possible.

Affected Projects

Any project that creates / uses SpeckleCache.db. PySpeckle creates a SpeckleCache.db file if none is found and enforces uniqueness.

Proposed Solution (if any)

When creating Account table in SpeckleCache.db, set RestApi and Email to be unique by doing UNIQUE(RestApi,Email).

I.e. '''CREATE TABLE Account ([AccountId] integer NOT NULL PRIMARY KEY AUTOINCREMENT,[ServerName] varchar, [RestApi] varchar, [Email] varchar, [Token] varchar, [IsDefault] integer, UNIQUE(RestApi,Email))'''
