Rounded values always 100 for some analyses

[MaximMoinat]

There are unintended calls to count_big of an already summed total in analyses queries that also calculate a numerical distribution. This issue was found in 25 analyses.
E.g. analysis 406:

CatalogueExport/inst/sql/sql_server/analyses/406.sql

Line 46 in 066b8e7

floor((count_big(o.total)+99)/100)*100 as count_value,

count_big(int) will always return 1, which rounds up to 100. (due to some quirks, I have also sometimes seen values of 200)

The equivalent Achilles analysis query does not contain a count at this level.

Proposed fix: remove count_big of a total.
