Array.concat does not work correctly when objects are passed as parameter.

Discussed in https://github.com/TypeScriptToLua/TypeScriptToLua/pull/737

Playground:

https://typescripttolua.github.io/play.html#src=%2F**%20%40noSelfInFile%20*%2F%0A%5B%5D.concat(13%2C%20323%2C%20%7Bx%3A%203%7D%2C%20%5B2%2C%203%5D).forEach(e%20%3D%3E%20console.log(e))

**Important:** add related tests.
