Jira password gets removed when saving GitLab project JIRA settings
This issue was originally found against GitLab-EE version 7.12:
When updating the Jira settings for a GitLab project: Admin Area > Projects Choose Project and hit "Edit" Services > JIRA On updating the settings and pressing "Save", if the JIRA user password was previously entered, it is removed on saving the updated settings.
When a password has been previously entered, there is no opportunity for the user to update or edit it before saving to work around this. Ideally some kind of validation should be carried out when updating settings to give the user a chance to re-set this password before saving.
