Issue Summary

• When using the "Test Connection" feature on an existing un-modified webhook in Bitbucket DC, it sends through a username and empty password.

This is reproducible on Data Center: (yes)

Steps to Reproduce

• Create a webhook and configure "Basic Auth" for the webhook by entering the username and password credentials
• Attempt to test the webhook by pressing the "Test Connection" button. Note that both the username and password are sent through on the auth header as expected
• Save the webhook and reload the page
• Without modifying anything in the basic auth section, run "Test Connection" again after reloading. The test request now only sends through a username and no password on the auth header

Expected Results

• Test Connection should send the configured username:password for existing webhooks where the basic auth fields have been unmodififed

Actual Results

• Reviewing the Request headers we notice that the test connection sends only the username with empty password.

Workaround

• Manually enter the password to perform the test connection.
