Fix html macro exception missing parameter value

[pmario]

This PR fixes the problem where a macrocall with an empty parameter causes the RSOD
Also see the discussion at Talk

To preproduce

• open tiddlywiki.com
• create a tiddler with this content: <<list-links '[tag[HelloThere]]' field:>>
• Activate the preview
• The RSOD comes up.

The problem is this line

var domNode = this.document.createElementNS(this.namespace,this.tag);

.createElementNS() allows the second parameter createElementNS(namespaceURI, qualifiedName) to be a HTML tag name.

In this case this.tag -> qualifiedName contains the value field: ... where the : colon throws an exception. ...

This PR

• creates an error message and
• writes the JS-error string to the console.

@Jermolene ... Do not merge yet, since we will probably need a new translatable error text

[pmario]

If add console-error to the Logger class #7125 is merged I'd like to use the logger.error() function to create a red error message on the dev console, instead of an almost invisible log() message

@Jermolene Your latest fix for the genesis widget didn't fix this problem

I had not seen this ticket.

Thanks @pmario I'm going with a slightly different fix which is to silently correct the tag name; it's consistent with what we already do with unsafe elements.
