[FIX] web: pivot model accept no __count key or null values

The _mergeData function used in pivot view comparison mode
was not designed to accept the absence of the __count key or
null values for measures in the objects returned by a 'read_group'.

The absence of the __count key would result in a traceback and null
values for measures into wrong calculations (infinities).

One could ask why null values did not cause problem before.
The simple reason is that the formatters used to format cell values
render a 'null' value like they render a zero.
This fix makes explicit that null values have to be considered
as zeros and avoid in that way Infinity values when computing
variations.
