Added profile images to /notifications and /_goal pages
• For /notifications page: Used the same approach of using forEach() and push() to match-merge `accounts` array to `notifications` array, in both initial data fetch `fetchNotifs()` and when updating notif class `updateNotifClass()`
• For /_goal pages: Used `try... catch` to prevent error page, in case there's a user without an account and GET request to findOne account fails
• Did you know? In Nuxt.js when using the nuxt/axios plugin, you can also disable the progress bar in specific requests using the progress option in an inline request configuration: https://axios.nuxtjs.org/options/#progress
`this.$axios.$get('URL', { progress: false })`
