This reverts commit 3d9f9b1b29.
Reason for revert: comment from sberg:
I'm not convinced that a general rule of "clear all references in dispose()" is a good idea. For example, in this class, access to connection_ and provider_ is not guarded against MT-races, on the basis that those two are never modified post construction. That is broken now. Also, e.g. Bridge::getDescription dereferences connection_, and benignly used to work fine even when called on a disposed instance. Now, it causes UB.
