Incorrect Tactics count

[IanDavila]

As a user of the ATT&CK website, I want to see the correct count of tactics on the tactics page (https://attack.mitre.org/beta/tactics/enterprise/).

To fix this, we should replace (

attack-website/modules/tactic.py

Line 48 in 82d24bb

'tactics_list_len': str(len(tactics))

) to 'tactics_list_len': str(len(tactics[domain])). This will return the correct tactic count per domain.
