[BUG] Print's options don't work with Text, but they do with str

Simple code:

```python3
from rich.text import Text
from rich import print

a = Text('aa', end='')
b = Text('bb', end='')
print(a, b, sep=' potatoes ', end='\n\n')
```

Should output:

```
aa potatoes bb


```

The actual output:

```
aabb
```

If you use `str` rather than Text, then it works properly.
