Fatal error when updating with invalid license

[jamesckemp]

Steps to reproduce:

1. Install 2 or more uplink-based plugins. (Flux and Account Pages on feature/uplink are a good option).
2. Set the version lower to those on PUE.
3. Enter an invalid license key for the plugin you want to update.
4. Try to update via update-core.php admin page.

Notes:

This issue only seems to occur when 2 uplink-based plugins are running. When there's only one, it displays a notice instead of a fatal error.

@defunctl seeing a couple more reports of this error in the wild via the helpdesk, although I don't have information yet around whether the invalid licensing portion of James's original report can be replicated here.

Do you have any capacity to take a look?

@davegreenwp I believe this PR that Ben opened is the fix, are you able to give it a try?

However, the PR is going to another branch so you may need to cherry pick it.

Got a PR open to main now: https://github.com/stellarwp/uplink/pull/66

@davegreenwp that's released here https://github.com/stellarwp/uplink/releases/tag/v1.4.2

Give it a try, however note that customers experiencing this issue would need to manually update their plugins.

thanks @defunctl I'll carve out some time tomorrow to pull these changes into the two plugins in question and get some pre-release copies to the customers who reported. I know at least one has a staging environment.
