Evaluating chunks via the eval command may swallow (some types of) errors

[rdw-software]

Example:

evo eval "print(56976*/3*4)"  -- Should raise an error, but doesn't

In LuaJIT:

luajit -e "print(56976*/3*4)"
luajit: (command line):1: unexpected symbol near '/'

However, something like this will indeed raise the error (as expected):

> evo eval "error(42)"
[string "error(42)"]:1: 42
stack traceback:
        [C]: in function 'error'
        [string "error(42)"]:1: in function 'chunk'
        Runtime/evo.lua:300: in function <Runtime/evo.lua:288>
        [C]: in function 'lua_pcall'
        Runtime/LuaVirtualMachine.cpp:135: in function 'RunCompiledChunk'
        Runtime/LuaVirtualMachine.cpp:110: in function 'DoString'
        Runtime/main.cpp:72: in function 'main'
> luajit -e "error(42)"
luajit: (command line):1: 42
stack traceback:
        [C]: in function 'error'
        (command line):1: in main chunk
        [C]: at 0x55625749c1d0

This should be easy to fix, but needs some additional test cases to avoid regressions.
