Mishandling of print function

The following code...
```
import redbaron
rb = redbaron.RedBaron('func = print if True else print')
print(rb.dumps())
```
...produces the following output:
```
func = printif True else print
```

Note that the space between the `print` and the `if` has been removed.

This bug does not occur if the the word `print` is replaced with `foo`.
