I fixed this issue by declaring caption variable, so it will never be null

I came across this error in one of our website's log.
I couldn't found the specific steps to reproduce.
However during backtracking the error, I noticed that my field formatter setting has configured `alt text` as caption text.

For the few migrated images, we had empty alt text.
That was causing issue.

I think adding null safe check should help in this case.
Created a PR with the relevant changes.

@mohit_aghera Thanks for the MR! I agree, the null-safe check is a prudent approach. I have merged your change.
