Summary:
This diff fixes the issue for label name (and edge type/property)
with spaces and special characters to avoid possible OpenCypher injections.
Consider an example where label name is 'hello :world'. `DUMP DATABASE`
used to return query which creates a node (u:hello :world) - i.e. node
that contains two labels 'hello' and 'world'. This fix escapes names to
create the following node with exactly one label as expected:
```
(u:`hello :world`)
```

Summary:
Now that unique constraint feature is added to Memgraph database,
we should update `DUMP DATABASE` with list of existing unique constraints.

Summary:
Previously, when accessing the labels/properties/edges of a vertex/edge that
was just created the NEW view would correctly display the change, but the OLD
view would be invalid and would crash the database. With this change the OLD
view of a freshly created vertex/edge won't cause a crash, but will instead
report an error.

Summary:
The dumper is now a function and doesn't have to worry about any state. The
function streams the Cypher queries directly to the client. This diff also
makes the dumper work with storage v2.
