[BUG] Cannot Access Associated Slot of Sender In Validation

[doublespending]

Describe the bug

Return Error when userOp uses ERC-20 as gas token in Paymaster. When I used alchemy or stackup bundler, the case can pass.

Paymaster: 0x07865c6e87b9f70255377e024ace6630c1eaa37f GasToken: 0x49040d242126f709b32623704e78bbe0991e6992

I suppose that it is not enough to just find onekeccak candidate: https://github.com/etherspot/skandha/blob/master/packages/executor/src/services/UserOpValidation.ts#L241

Ref other bundler implementations:

• https://github.com/eth-infinitism/bundler/blob/main/packages/bundler/src/parseScannerResult.ts#L249-L272
• https://github.com/stackup-wallet/stackup-bundler/blob/main/pkg/entrypoint/simulation/storageslots.go#L44-L54

Error: 0x49040d242126f709b32623704e78bbe0991e6992 is the gas token address not a paymaster.
