Fix max parameters Count

[Red1408192]

I suggest a fix in this section here
I recently got stucked by the really unlucky scenario where the parameters count can exceed the number allowed by sql server

Related issue: #138

i have also suggested a slight performance improvement and reduced the parameters cap by 10, just for safety

fixed, the tests require the exact same order for the parameters to pass, so i had to recalculate before hand the update expressions. tecnically it wouldn't have been a bug, but instead of updating all the unit tests i prefered to do like so

Hey @Red1408192, apologies for only picking this up now

I went through the code, and I realised that you never actually changed the order of arguments being inserted, so the updated code could be.. simplified.. back to the original way of indexing arguments.

You're absolutely right that I completely forgot about taking into account the update expression and the condition constants.. I've further optimised it to calculate them only once into the singleEntityArguments variable, since that was the purpose of it :)
