Capability with number given as string type is updated to a different number

**Describe the bug**
Any Capability with a value of long number more than 16 digits in string format is updated to a different number.

**To Reproduce**
1. Install botium-cli and botium-connector-fbwebhook
2. Clone the botium-connector-fbwebhook repo and start the sample botkit server
3. Use the following given botium.json
4. Start the emulator in verbose mode using `botium-cli emulator -v`
5. Send a message and observer the payload that the emulator sent. The `sender.id` would be of different number than what we have set in the botium.json

```js botium.json
{
"botium": {
"Capabilities": {
"PROJECTNAME": "Facebook Tests",
"CONTAINERMODE": "fbwebhook",
"FBWEBHOOK_WEBHOOKURL": "http://127.0.0.1:3000/api/messages",
"FBWEBHOOK_PAGEID": "123456",
"FBWEBHOOK_APPSECRET": "mysecret",
"SIMPLEREST_INBOUND_PORT": 45100,
"SCRIPTING_MATCHING_MODE": "equals",
"FBWEBHOOK_USERID": "1234567892343434344"
}
}
}
```

**Expected behavior**
The payload sent should have same sender.id that we set using `FBWEBHOOK_USERID` in the botium.json
