Collection creation stuck in an infinite writeConflictRetry loop when having a duplicate name as a view

When creating a collection implicitly, we check if a collection with the namespace string already exists. However, before committing, we also check that if the nss conflicts with another view. As a result, if one thread successfully creates a view while another one is attempting to create a collection with the same nss in the writeConflictRetry loop, the other thread could fall into an infinite loop.
