`DataViewModel.showHover: false` not respected

[amcclain]

You can see this in our Toolbox example - https://toolbox-dev.xh.io/app/grids/dataview. We don't have switches on this example to turn on/off row hover highlights, but it is off by default and we're still getting the highlight.

You can inspect the dataview grid element to verify - it has the .xh-ag-grid--no-hover class applied.

Interestingly, standard grids appear to work OK.
