potential fix for raw JSON output with conversions

[035WasTaken]

Noticed an issue with trying to convert something like "60minutes to seconds" where the bot would output raw JSON (Ie check for if (result.mathjs) fails and falls to the else if (typeof result == 'object') block which then just outputs the raw JSON result object as opposed to result.value. I have no clue if this is a symptom of a larger issue or not, but the change provided here is a quick solution that does fix the issue described above. At the very least, let this draw your attention to this issue, and hopefully you can find a more elegant solution than this.

Example:

Input:

owo math 60minutes to seconds

Output:

the answer is: {"units":[{"unit":{"name":"seconds","base":{"dimensions":[0,0,1,0,0,0,0,0,0],"key":"TIME"},"prefixes":{"":{"name":"","value":1,"scientific":true},"deca":{"name":"deca","value":10,"scientific":false},"hecto":{"name":"hecto","value":100,"scientific":false},"kilo":{"name":"kilo","value":1000,"scientific":true},"mega":{"name":"mega","value":1000000,"scientific":true},"giga":{"name":"giga","value":1000000000,"scientific":true},"tera":{"name":"tera","value":1000000000000,"scientific":true},"peta":{"name":"peta","value":1000000000000000,"scientific":true},"exa":{"name":"exa","value":1000000000000000000,"scientific":true},"zetta":{"name":"zetta","value":1e+21,"scientific":true},"yotta":{"name":"yotta","value":1e+24,"scientific":true},"deci":{"name":"deci","value":0.1,"scientific":false},"centi":{"name":"centi","value":0.01,"scientific":false},"milli":{"name":"milli","value":0.001,"scientific":true},"micro":{"name":"micro","value":0.000001,"scientific":true},"nano":{"name":"nano","value":1e-9,"scientific":true},"pico":{"name":"pico","value":1e-12,"scientific":true},"femto":{"name":"femto","value":1e-15,"scientific":true},"atto":{"name":"atto","value":1e-18,"scientific":true},"zepto":{"name":"zepto","value":1e-21,"scientific":true},"yocto":{"name":"yocto","value":1e-24,"scientific":true}},"value":1,"offset":0,"dimensions":[0,0,1,0,0,0,0,0,0]},"prefix":{"name":"","value":1,"scientific":true},"power":1}],"dimensions":[0,0,1,0,0,0,0,0,0],"value":3600,"fixPrefix":true,"skipAutomaticSimplification":true}```
