Fixed profile image rendering bugs/edge cases on profile page, blog

I'd been mistaken how javascript operators work, like == ||

The logic: if variable is either null or empty, then do this.

❌ v-if="accDetails.profileImg == null || ''"
❌ v-if="accDetails.profileImg == (null || '')"
βœ… v-if="accDetails.profileImg == null || accDetails.profileImg == ''"
