fluids: Fix mass matrix for explicit time stepping

The local vector should be initialized to zero so that all the essential
nodes (ie. strong boundary condition nodes) are not factored in for the
matrix multiply. The PR associated with this commit should have a
document attached detailing why this is the case.

Previous tests used this incorrect mass matrix and so now fail. The
results for these tests are corrected as well.

Fluids - More Regression Tests (#687)

* examples/fluids: Regression tests: Changed the reference files' names and
the flags to associate with the corresponding example (so far
density_current only)

Changed the files' names

Changed the flags

* examples/fluids: added new regression tests for advection(2d)

* examples/fluids: regression tests: removed the enums and passed defined command-line options for filepath and test tolerance.
Removed solver controls and assigned testtol=1E-11 for explicit cases.

style

examples/fluids: regression tests: fixed the pathfile issue (it needs to be relative)

examples/fluids: Specified a name for each test

examples/fluids: TESTARGS - trying absolute path for the test files

* tests/tap.sh: Print out test names for fluids examples

inspired-by: @jeremylt

tests/tap.sh: drop quotation marks from the printed test names

* tests: specify test name for ceed and nek examples and print the names when there are multiple test arguments

* examples/fluids: remove test_ from test names

* style

* tests/junit.py: Add name for tests with multiple test cases

* examples/ceed/ex1-volume.c: make the naming of the tests consistent

* tests/junit.py: a more compact if statement

helped-by: @jeremylt

* examples/fluids: drop the broken supg test of density_current for now

The stabilization enum is not passed to density_current QFunction hence
the test doesn't work. We need to create a new test when the code is
debugged.
