Relax, that shopkeeper is an idiot for making such ridiculous assumptions. Nobody can say for sure that the reason for that accident was upsized tyres for sure. An accident occurs when everything that can go wrong DOES go wrong and conditions go completely out of your control, just one factor like tyres can't be blamed directly.

I have been upsizing tyres since the age of Yamaha RX100, never had an accident because of upsizing (or for any other reason). But you need to know the obvious disadvantages especially in a motorcycle like R15:
Acceleration is not as aggressive & instant like before.
Increased contact patch results in increased rolling traction, hence lower top-speed.
Front is not as agile as before, flicking & leaning requires a little more effort than before.
Increased braking distance.
Slightly inaccurate odometer readings because of change in tyre's circumference.

But these are all minor disadvantages which are negated completely by the advantages of upsizing - better grip, better braking, less chances of wheelspin and skids!
Basically just start braking a little earlier than before and you are good to go, stop worrying about probabilities, in fact you can decrease your probability of accidents to almost zero by becoming a skilled and safe rider. If you have not already done so, learn COUNTER-STEERING. It's THE ONE technique which improves your handling, you will start leaning in even on wet roads just like those MotoGP riders!
