Tweaked profile page to use .account id instead of author id

• Realised that it's not always the case that the account id will match the author id, so had to change the GET request for `accounts` to use the account id instead of author id

this.$axios.$get(`/acc.../${this.loggedInUser.account}`)

🚨 IMPORTANT to check through tomorrow that all the GET requests for `accounts` is using the accont id instead of author id!!!
