no methods for SearchLight.query causing issues in last_up?

I am going through the tutorial in the docs (which is great btw) and can't seem to figure out [this part ](https://geniejl.readthedocs.io/en/latest/guides/Working_With_Genie_Apps_Intermediary_Topics/).

After running ```SearchLight.Generator.newmigration``` I get the migrations file just fine - it looks like so:

```
module AddCoverColumn
import SearchLight.Migrations: add_column, add_index

function up()
add_column(:books, :cover, :string)
end

function down()
# I am using SQLite
end

end
```

However, when I run either ```SearchLight.Migration.last_up()``` or ```SearchLight.Migration.status()```, I get the following:
```
ERROR: MethodError: no method matching query(::String; internal=true)
Stacktrace:

[4] last_up() at C:\Users\dvets\.julia\packages\SearchLight\0MG55\src\Migration.jl:118
[5] top-level scope at none:1
```

But if I run ```methods(SearchLight.query)``` it returns no methods...

I'm pretty far out of my depth here so I'm not sure what I am getting wrong.
