Suggests that tsconfig.json is incorrect only when SyntaxError is caught

Created by: Andarist

Otherwise I get i.e. such output;

Could not parse tsconfig.json. Please make sure it contains syntactically correct JSON.
Details: tsconfig.json(19,12): error TS1328: Property value can only be string literal, numeric literal, 'true', 'false', 'null', object literal or array literal.

Which is misleading - especially taking into account that info about incorrect JSON is written in bold
