Handle bad layers fails on a bad WMS layer

When opening a QGIS project with missing/bad WMS layer, "handle bad layers" dialog offers to select a file(!) to fix the issue. The provider is displayed as "none", although in .qgs file it is "wms". Offering a file open dialog to fix WMS issue isn't helpful at all. Together with #17436 it makes opening such projects a real pain.

An ultimate solution should contain following options:

• offer a text edit option for the DSN (i.e. I would be happy to just right click on layer source and edit it to replace old WMS server address with a new one);
• use data provider dialog to point to the bad (missing) layer;
• offer an option to mark layer as "unavailable" (see Do not remove unavailable layers when opening project #17436 for rationale).

Related issue dealing with importance of missing/bad layer handling enforcement: #16129
A variation of this issue but caused by changes in QGIS supported data providers: #14083

Tested with QGIS 302ad06 on GNU/Linux.
