Final words

I've run into a bug in which the final words in a string are not linted properly.

For example:

With this rule set up:

```
"terminology": {
"defaultTerms": true,
"terms": [
"ID"
]
}
```

The following object would not be linted properly:

```
"parameters": [
{
"in": "query",
"name": "merchantIds",
"description": "The merchant id"
}
]
```

While this one would:

```
"parameters": [
{
"in": "query",
"name": "merchantIds",
"description": "The merchant id to be found"
}
]
```
