Strict SW catalog image checking.

[revanth0212]

Description

@Jordaneisenburger has explained the issue at hand very well in the related issue.

It is a fairly simple fix. All we have to do is to compare the file names instead of checking for text includes.

I could not replicate the issue at hand because could not find URLs like mentioned in the issue. But, I have tested the SW cache handling and it works fine.

@Jordaneisenburger it would be great if you can validate the issue against this PR.

Looks good, and I've confirmed on a local that it does resolve the bug. I assume a test will come later, but nice work 👍
