iOS code generation can cause runtime exception if number of parameters is not the same as the localization format

[leonardowf]

Right now, if you by mistake provide one less argument to the Localicious format, the string replacement throws a run time exception.

The problem:

The following example string: "Screen.Component.Button.ACCESSIBILITY.LABEL" = "%1$@%2$@, hello %3$@.";

when replaced with two arguments result in an EXC_BAD_ACCESS exception

Proposal

Count the number of arguments and placeholders and avoid the exception if they don't match
