Fixed
- Fix subgraph generation when a segmentation was defined as context and the
match includes a token that is not covered by a segmentation node (there are
gaps in the segmentation). This is achieved by explicitly searching for all
token between the first and last matched segment and produces a more complex
query than before. Because token where missing from the graph, it could appear
in ANNIS that there are gaps in the data and that the token order is
incorrect.
