Receive the two values returned from get_instance()

`get_instance()` returns two values. Old code, instead of unpacking two
values in two variables, placed the tuple in a single variable
`pelican`.

Later in the same block when `pelican.run()` was called, it resulted in
error.

```
-> Modified: content, theme, settings. re-generating...
CRITICAL: ("'tuple' object has no attribute 'run'",)
CRITICAL: 'tuple' object has no attribute 'run'
Traceback (most recent call last):
  File "/Users/talha/Repos/VirtualEnvs/pelican-dev/bin/pelican", line 8,
  in <module>
    load_entry_point('pelican==3.3', 'console_scripts', 'pelican')()

```

Either the returned value should be unpacked properly or
`pelican[0].run` should be called.
