When you create connection profile without password defined and try to add the password during import, TD ignores this password.

You have to change/insert the password in the connection profile definition dialogue.

See steps to reproduce and screenshots in JIRA

STEPS TO REPRODUCE:
1. Create JDBC connection profile without password defined
2. Try to import from this connection profile
3. Insert password in "Select a JDBC source configuration" dialogue
4. TD says that password is null
