AK: Pass correct length to StringUtils::convert_to_floating_point()

Browse source 
Fixed the issue in StringUtils::convert_to_floating_point() where the
end pointer of the trimmed string was not being passed, causing the
function to consistently return 'None' when given strings with trailing
whitespaces.
