What happen if a wire is connected in parallel to a capacitor?
Ideally all the current will flow through the short and that is what you should consider absolutely true at this stage in your learning. 

In reality wires have resistance and inductance (and capacitance) and capacitors have inductance and resistance as well as capacitance. So if you have a (real) long-ish wire in parallel with a (real) well-made capacitor some significant part of the current may flow through the capacitor at higher frequencies. This will not show up in a simulation unless the imperfections are modelled.
