[Emacspeak] Patch: make emacspeak-tabulated list play nice with list-packages

[Parham Doustdar <parham90@xxxxxxxxx>]

Hi,
I get an error when doing `C-h p’ and going to the leftmost cell in the table using the left/right arrow keys. This is because Emacspeak tabulated list expects all fields to be strings. All the emacspeak-package.el functions take this into account, but tabulated list doesn’t. So I added a check to treat the first element as the “value” below:
