uglify option broken

If using the `-u` option, the output is broken. I didn't check it all but there's a few places where a semicolon is missing between statements.

**To reproduce ** :
```
$ rapydscript --version
rapydscript-ng 0.7.19

$ rapydscript <(echo 'print("Hello world")') | node
Hello world

$ rapydscript -u <(echo 'print("Hello world")') | node
[stdin]:1
(function(){"use strict";var ρσ_iterator_symbol=(typeof Symbol==="function"&&typeof Symbol.iterator==="symbol")?Symbol.iterator:"iterator-Symbol-5d0927e5554349048cf0e3762a228256";var ρσ_kwargs_symbol=(typeof Symbol==="function")?Symbol("kwargs-object"):"kwargs-object-Symbol-5d0927e5554349048cf0e3762a228256";var ρσ_cond_temp,ρσ_expr_temp,ρσ_last_exception;var ρσ_object_counter=0;var ρσ_len;function ρσ_bool(val){return!!val};if(!ρσ_bool.__argnames__)Object.defineProperties(ρσ_bool,{__argnames__:{value:["val"]}});function ρσ_print(){var parts;if(typeof console==="object"){parts=[];for(var i = 0; i < arguments.length; i++){parts.push(ρσ_str(arguments[(typeof i==="number"&&i<0)?arguments.length+i:i]))}console.log(parts.join(" "))}};function ρσ_int(val,base){var ans;if(typeof val==="number"){ans=val|0}else{ans=parseInt(val,base||10)}if(isNaN(ans)){throw new ValueError("Invalid literal for int with base "+(base||10)+": "+val)}return ans};if(!ρσ_int.__argnames__)Object.definePr

In the resulting file, I see this for example :
`hasattr = ρσ_hasattrfunction `
and
```
Object.defineProperty(ZeroDivisionError.prototype, "__bases__", {
value: [Exception]
}) var ρσ_in, ρσ_desugar_kwargs, ρσ_exists;
```

Start by reproducing the `rapydscript -u` command from the issue and compare its output with the non-uglified command under Node. Trace the CLI entry point for `-u` and the generated JavaScript around the reported missing semicolons. Done means uglified output parses and prints `Hello world` successfully.
