[FIX] compiler: better support for arrow function and function call

This commit fixes inline expressions when we have these conditions:
* inline expression that contains an arrow function
* inside the arrow function call a function with multiple arguments (3+)
* the second argument (not the first and not the last) must be a variable

In the `compileExprToArray` we have a code to handle missing tokens in an object
e.g.: {a} (equivalent to {a:a})

When OWL match all 3 conditions listed above we execute the code to handle
the missing tokens and so it alter the tokens and adds a new token:
`{ type: "COLON", value: ":" }`
This result in a Javascript compilation error:
OwlError: Failed to compile template "XXX": missing ) after argument list

To fix the error and avoid execute the code to handle the missing tokens, now,
we track also the parentheses in our local stack.
