fix: print all dep-graphs of a container scan

[mcombuechen]

What does this PR do?

When printing the dep-graph results from Snyk container SCA, the code would escape early and omit all the dep-graphs that might have been found during remote analysis. This commit moves the dep-graph printing during container SCA to after the remote analysis call, this way including additional dep-graphs of applications within the container image.

First pass looks good! See suggestion below to help this scale better for large objects. Heap space is unfortunately capped in the NodeJS process though, which can lead to incorrect outputs (or possibly process crashes due to OOMs). We have a couple open tickets where containers have tripped this limit.

Too much happening, too much failing, tap is driving me up the wall. Will open smaller-scoped PRs instead.

@cmars will close this in favour of two other PRs.
