Adding multiple links on an issue fails if one of the links is not valid.

Issue Summary

If you attempt to add multiple links to an issue and one of the links is not valid, Jira will not add the other valid links.

Environment

Any fresh install.

Steps to Reproduce

1. Step 1
   Add 2 valid links between two or more issues.
2. Step 2
   Add an invalid link between two issues (for instance, use an inexistent issue key).

Expected Results

Jira should add the valid links and disregard the invalid link.

Actual Results

Jira does not add any of the links and presents an error message acknowledging that there is an invalid link.

Workaround

The workaround available is to add links one by one.
