Fixed data rendering issue of profile image on profile page

• Added additional v-if="accDetails" to
profile image, in case a particular account doesn't exist in the data table - to prevent error when at the next v-if="accDetails.profileImg lower down the template (if account doesn't exist, accDetails would be undefined and .profileImg would be trying to read from an undefined variable, which will result in an error)

• Added additional v-else to show robo avatar if account indeed doesn't exist

• Overall, the logic looks like this:
--- v-if - if account exists
------ v-if - if image is null or empty, show robo
------ v-else - if image exists, show image
--- v-else - if account doesn't exist, show robo

• also added try {} catch {} to the function for the accDetails endpoint to prevent error from stopping the page from rendering
