a tiny bug in the script of circuits package

[FoodChain1028]

in the snarkBuild.ts script:

this line should not be in the else block, but in the end of the function

create-unirep-app/packages/circuits/scripts/buildSnarks.ts

Line 92 in e429d3a

process.exit(0)

If there are more than one circuits in circuits folder, the current script will find the first circuit that doesn't have the files in zksnarkBuild/ and build with the dependencies. However, it should compile all the circuits that haven't had the dependencies.
