[PDI-11048] PDI - EE: Connection names displayed incorrectly in the repository view

DatabaseMeta getName() was used to display the connection names when creating a connection in the repo.  We were encoding this name (removing JCR reserved characters and replacing with an underscore).  The encoded connection name was displayed in the UI.  Now we display the un-encoded connection name in the UI.

Note: There is a corresponding fix in the pdi-ee-plugin git repo.  Will issue a pull request after this one.  No build dependency.
