Var.shape and Var.init.shape do not match

[erik-ski]

Describe the bug
It is possible to create a Var object whose declared shape and "real shape" (i.e. the shape of the array it holds, passed as the init parameter) differ.
To reproduce current behavior
Steps to reproduce the behavior:

1. When I run this code

def my_code():
  shape = (2,2) # innocent shape declaration
  weights = np.array([[1, -1], [-1, 1]]) # init value, corresponding to the shape
  v = Var(shape=(shape, shape), init=weights) # wrong/strange shape declaration (this is similar to the first block of code from tutorial02_ecxitatory_inhibitory_network.ipynb)
  print(v.shape)
  print(v.init.shape)
if __name__ == "__main__":
  # the var shape attribute and the init value shape should match?
  my_code()

2. I get this error ...

shapes won't match

Expected behavior
an AssertionError should have happened impeding me to declare such a Var

Environment (please complete the following information):

• Device: Laptop
• OS:Ubuntu Linux 20.04
• Lava 0.9.0

Additional context
I found this in the first block of code from tutorial02_ecxitatory_inhibitory_network.ipynb, in the line

self.weights = Var(shape=(full_shape, full_shape), init=weights)

The tutorial is from the commit 5ed88f7
