bug(token-blueprint): utils.toNumber() would error if it was used

[dvinubius]

Problem

The token blueprint has

local utils = {
  -- ...
  toNumber = function(a) return tonumber(a) end
  -- .. 
}

The function errors for bint inputs. It intended specifically to facilitate usage of bints though.

It's currently not used, so the bug was not observed yet.

Solution

Should be

return bint.tonumber(a)
