Bug fix of spawn truffle

[vporton]

Description

Both

spawn('node_modules/.bin/truffle', ['migrate', '--reset', '--compile-all'], ...

and

spawn('./node_modules/.bin/truffle', ['migrate', '--reset', '--compile-all'], ...

fail on my Ubuntu Linux, even despite I create a symlink from ./node_modules/.bin/truffle to truffle binary.

So, I fixed this bug.

Changes 🏗

• Add npx when spawning truffle.
