Sequential DataFrame joining error
I ran across a case where multiple DataFrame joins will sometimes fail, depending on how the DataFrames are partitioned.

The below example does sequential inner joins (i.e. `df1.join(df2, how='inner').join(df3, how='inner')`) using pandas DataFrames and then using dask DataFrames. 

```python

import pandas as pd
import dask.dataframe as dd
from dask.dataframe.utils import assert_eq

# Pandas version of multiple inner joins
df1 = pd.DataFrame({'key': list(range(6)),
                    'A': ['A0', 'A1', 'A2', 'A3', 'A4', 'A5']})
df2 = pd.DataFrame({'key': list(range(4)),
                    'B': ['B0', 'B1', 'B2', 'B3']})
df3 = pd.DataFrame({'key': list(range(1, 5)),
                    'C': ['C0', 'C1', 'C2', 'C3']})

join_pd = df1.join(df2, how='inner', lsuffix='_l', rsuffix='_r')
multi_join_pd = join_pd.join(df3, how='inner', lsuffix='_l', rsuffix='_r')
print(f'join_pd = {join_pd}')
print(f'multi_join_pd = {multi_join_pd}')

# Dask version of multiple inner joins
ddf1 = dd.from_pandas(df1, npartitions=3)
ddf2 = dd.from_pandas(df2, npartitions=2)
ddf3 = dd.from_pandas(df3, npartitions=2)

join_dd = ddf1.join(ddf2, how='inner', lsuffix='_l', rsuffix='_r')
multi_join_dd = join_dd.join(ddf3, how='inner', lsuffix='_l', rsuffix='_r')
print(f'join_dd.compute() = {join_dd.compute()}')
print(f'multi_join_dd.compute() = {multi_join_dd.compute()}')
```

The pandas case works as expected, however the dask case fails on `master`.

Interestingly, the failure is partition-dependent. For instance in the above example, if you change the partitions for `ddf1` so that `ddf1 = dd.from_pandas(df1, npartitions=2)`, then the sequential joining of dask DataFrames works.
