Describe the bug

When you try to clone 0x06bdf212c290473dcacea9793890c5024c7eb02c it errors i am guessing it will error for other contracts, this should work out the box i think.

All the files are imported correctly but the generated remapping is invalid:

forge-std/=lib/forge-std/src/
SystemStart.sol/=src/SystemStart.sol/
IBoostDelegate.sol/=src/IBoostDelegate.sol/
ITokenLocker.sol/=src/ITokenLocker.sol/
IEmissionSchedule.sol/=src/IEmissionSchedule.sol/
IPrismaCore.sol/=src/IPrismaCore.sol/
draft-IERC20Permit.sol/=src/draft-IERC20Permit.sol/
IPrismaToken.sol/=src/IPrismaToken.sol/
IIncentiveVoting.sol/=src/IIncentiveVoting.sol/
SafeERC20.sol/=src/SafeERC20.sol/
IBoostCalculator.sol/=src/IBoostCalculator.sol/
Address.sol/=src/Address.sol/
PrismaOwnable.sol/=src/PrismaOwnable.sol/
IERC20.sol/=src/IERC20.sol/
Vault.sol/=src/Vault.sol/

To temporarily work around it remove the remappings and rewrite import "SafeERC20.sol"; as import "./SafeERC20.sol";
