You can create invalid library names with Mongo backend

[jamesmunro]

Describe the bug

ArcticDB lets me create an unusable library with a / on MongoDB backend. / is not a valid char for a Mongo database name.

Steps/Code to Reproduce

import numpy as np
import arcticdb as adb

arctic = adb.Arctic('mongodb://localhost:27017')
a.create_library('a/b')
lib = a.get_library('a/b')
lib.write('c', np.array([1, 2, 3]))

Fails with

StorageException: E_UNEXPECTED_MONGO_ERROR Unexpected Mongo Error: MongoError#73: mongodb generic server error Invalid database name: 'arcticc_a/b': generic server error

Expected Results

create_library should fail instead
